累进性劳动所得税、失业波动与内生稳定器——一个动态新凯恩斯主义的视角

将累进性劳动所得税引入NKMP—DSGE模型中考察失业波动与累进性税收的宏观效应。贝叶斯脉冲响应函数表明,外生冲击对于就业与失业具有不同的冲击效应,因而忽略失业可能引起结论的偏误;失业的贝叶斯冲击分解结果表明,货币政策冲击是推动我国失业波动最重要的力量,并且我国劳动力市场存在显在的“失业回滞”。进一步,通过模型比较发现,累进性劳动所得税具有内生稳定器的作用。在失业问题日益严峻的背景下,采用对劳动力市场做出反应的货币政策机制以降低失业,并使用内生稳定器缓和经济波动,将可能实现降低失业与缓和经济波动的双重效果。     

What goes up sometimes stays up: shocks and institutions as determinants of unemployment persistence

We analyse the determinants of unemployment persistence in four OECD countries by estimating a structural Bayesian VAR with an informative prior based on an insiders/outsiders model. We explicitly insert unemployment benefits and labour taxes so that our identification is not affected by the Faust and Leeper (1997) critique. We find widespread hysteresis: demand shocks play a dominant role in explaining unemployment also in the medium‐run. Moreover real wages have low sensitivity to cyclical fluctuations and to labour market disequilibria. Our results emphasise the real power of the unions and their interactions with structural shocks and other institutions as crucial determinants of hysteresis.     

A strong hysteretic model of Okun’s Law: theory and a preliminary investigation

This paper presents a ‘strong hysteretic’ version of Okun’s Law, that is, a version of the law in which ‘history matters.’ In this version of the link between fluctuations in unemployment and growth, the most important past growth shock exerts an influence on the current unemployment rate. A theoretical framework is proposed in order to lay the foundations of this version of Okun’s Law. In this framework, the hysteresis property arises because a large number of heterogeneous firms discontinuously adjust their activity levels in response to fluctuations in the rate of growth. The foundations having been laid, a method for empirically testing our hysteretic Okun’s Law is presented. An algorithm permits construction of a hysteresis operator, which synthesizes, for every moment, the growth shocks that have remained in the memory bank of the unemployment rate. Empirical tests are conducted to assess the empirical relevance of this version of Okun’s Law, as compared to the more familiar linear relationship. Empirical results consistent with hysteresis are found for several of the countries in our sample.     

The Macroeconomic Consequences of Long-Term Unemployment

This article examines the linkages between long-term unemployment and two important recent debates in Australia: first, whether unemployment exhibits hysteresis tendencies; second, the nature of the relationship between unemployment and real wages. Our findings favour the hysteresis account in that the evidence rejects an equilibrium relationship between long-term and total unemployment. Also, the effect on real wages of an increase in the number of longterm unemployed is found to be both positive and significant.     

Testing for hysteresis in unemployment an unobserved components approach

We suggest a new test for hysteresis in unemployment based on an unobserved components model. Observed unemployment rates are decomposed into a natural rate component and a cyclical component. The impact of lagged cyclical shocks on the current natural component is the measure of hysteresis. To identify the two components of unemployment, we assume that the cyclical compoentn is correlated with capacity utilization. The model is applied to U.S. and German data. We find no evidence of hysteresis in U.S. data. German unemployment rates exhibit substantial hysteresis. A shock of 1.0 percent to the current cyclical component permanently increases future German natural rates by about 0.5 percent. For both countries, natural rate shocks turn out to be an important impulse mechanism to explain movements in observed unemployment rates.     

Testing hysteresis effect in U.S. state unemployment: new evidence using a nonlinear quantile unit root test

We revisit hysteresis effect in the unemployment rate of each of the 52 states of the United States using nonlinear quantile unit root test over the period 1976M1–2016M7. Our results indicate that unemployment rate of the U.S. economy as a whole displays hysteresis effect over recessionary periods. Nineteen out of 52 states display hysteresis behaviour over the period 1976–2016. For the remaining 33 states, we find four types of behaviours. Some states display stationarity behaviour almost in all quantiles. Some display hysteresis over recessionary periods and in contrast some display hysteresis over expansion period.     

The European unemployment problem: its cause and cure

The stubbornly high unemployment experienced by European countries since the mid-1970s have led to a major reconsideration of the natural rate paradigm. Traditional theories which describe movements of unemployment as fluctuations around a moving natural rate have been challenged by hysteresis theories. The question arises how one can discriminate between these competing theories. To this end, we estimate a time-varying parameter model of the unemployment rate for the US, UK, Germany, and France. The parameters of the model were estimated jointly by maximum likelihood estimation using the Kalman filter algorithm. When the moving natural rate model is tested against the alternative of a unit root process, the unit root hypothesis is resoundingly rejected. Among the determinants of the natural rate institutions that alter labour market incentives for workers appear to have been more important than institutions that affect labour demand.     

The presence of unemployment hysteresis in the OECD: what can we learn from out-of-sample forecasts?

This paper investigates the relevance of unemployment hysteresis in seventeen OECD countries. We employ an out-of-sample forecast exercise in which a mean-reverting autoregressive model is compared to an autoregressive model with an imposed unit root. A substantial difference in forecasting performance between the two models is established for many countries, but the results are mixed in their strength. The evidence for unemployment hysteresis in Austria, Finland, Iceland, Israel, Italy, Japan and Sweden is, however, convincing. For no country can unambiguous support for a mean reverting unemployment rate be found.     

HYSTERESIS HYPOTHESIS IN UNEMPLOYMENT AND LABOUR FORCE PARTICIPATION RATES: EVIDENCE FROM AUSTRALIAN STATES AND TERRITORIES *

This article simultaneously investigates the hysteresis hypothesis of unemployment and labour force participation using regional level data in Australia. The conventional univariate and panel unit root tests indicate that the hysteresis hypothesis cannot be rejected for most of the regions in Australia. To further confirm if the hysteresis finding in unemployment and labour force participation results from not considering structural breaks. We employ a panel stationarity test recently developed by Carrion‐i‐Silvestre et al. (2005 ), which considers multiple structural breaks and cross‐sectional dependence. The test results lend support for unemployment hysteresis and participation regime‐wise stationarity. Accordingly, the findings imply that a temporary shock may have permanent effects on the unemployment rate but not on labour force participation in Australia and thus call for policies aimed at improving the adjustment mechanism in unemployment.     

Hysteresis and sluggishness in Portuguese unemployment, 1977–88

The phenomenon of unemployment persistence led to the development of alternative theories of unemployment. Among these the ‘hysteresis’ concept by Blanchard and Summers (1987) received a wide interest. Based on this notion we developed a generalized model that nests Blanchards and Summers' theory. Using this framework we conducted an empirical investigation for the Portuguese labour market (1977–88). The results obtained point towards the existence of labour demand sluggishness, wage inertia and unemployment hysteresis. The model also suggests the existence of a rather inelastic labour demand curve.     

Testing for hysteresis: Unemployment persistence and wage adjustment

This paper proposes a new testing strategy for unemployment hysteresis as the joint restriction of a unit-root in the unemployment rate and no feedback effect of unemployment in the Phillips wage equation. The associated test statistics are derived when this joint restriction is imposed and when a sequential two steps testing strategy is adopted. An empirical application leads to reject the null hypothesis of wage hysteresis for most of our OECD countries. Evidence against hysteresis is reinforced when accounting for wage adjustments in the bivariate approach.

Hysteresis versus natural rate in Taiwan's unemployment: Evidence from the educational attainment categories

This study examines the hysteresis hypothesis in unemployment for Taiwan's educational attainment categories. Both nonlinear dynamics and structural breaks in unemployment are applied in our examinations. The empirical results without structural changes show that the unemployment hysteresis hypothesis cannot be rejected in all educational attainment categories. After simultaneously incorporating nonlinear processes and smooth structural changes, we find that only the unemployment rate of junior college graduates reveals a mean reverting to the natural rate in the long-run, whereas all other series still support the hysteresis hypothesis. The results indicate that: i) the shocks have only temporary effects on the unemployment rate of the junior college graduates; ii) the labor or macroeconomic stabilization policies could have long lasting effects on unemployment rates of the other educational attainment categories; iii) the unemployment rates of low-skill labor are susceptible to the changes of economic or fiscal policies; and iv) practical and occupational training mechanisms should be implemented and strengthened in the higher education system to alleviate the increasingly serious problem of unemployment.     

Flexible Fourier unit root test of unemployment for PIIGS countries

In this empirical study, we apply the flexible Fourier unit root test proposed by Enders and Lee (2012) to re-examine the hysteresis hypothesis of unemployment for PIIGS (Portugal, Ireland, Italy, Greece, and Spain) countries over the period from 1960 to 2011. We find that the Fourier unit root test has greater power than a linear method if the true data generating process of unemployment is a stationarity, non-linear process of an unknown form with structural change. The hysteresis in unemployment is confirmed for all PIIGS countries, with the exception of Portugal and Spain, when the Fourier unit root test is conducted.     

Inflation Rate Variability and the Phillips Curve

This paper studies the relationship between inflation and unemployment by focusing on the effect of inflation rate uncertainty on real wages, employment and output. The effect of inflation on employment is shown to depend on the relationship between the mean rate of inflation and the variability of its forecasts. This can explain why the Phillips curve is negatively slopped in some periods and undetermined or positively slopped in others.     

Unemployment by Gender: Evidence from EU Countries

This paper applies panel unit-root tests that allow for structural breaks and cross-sectional dependence to examine the validity of hysteresis in gender unemployment rates and gender unemployment gap for a panel of 15 European countries. Addressing breaks, there is evidence to reject the null hypothesis of hysteresis for the unemployment rates and unemployment gap series. Allowing for both cross-sectional dependence and heterogeneous structural breaks, this result is reverted, and we fail to reject the null hypothesis of unit root.     

Insider Power as a Source of Hysteresis in Unemployment: Tests with Australian Data

This paper reports the results of an empirical investigation of hysteresis in the unemployment rate using Australian data for 1966(3)-1988(4). It is found that there is not hysteresis in the strict sense of the irrelevance of the natural unemployment rate although there is strong evidence of insider power in the wage-fixing process. There is no evidence that the Accord changed the extent of the influence of insider power on wage setting.     

Unemployment hysteresis and the natural rate of vacancies

On the basis of macro data from 10 OECD countries, I find that the job vacancy rate outperforms the unemployment rate as a reliable measure of domestic inflationary pressure. Moreover, while the rate of unemployment affects inflation primarily through its difference, the vacancy rate operates through a level effect as well. In most countries, a unique equilibrium rate of vacancies seems to coexist with a drifting equilibrium rate of unemployment. I show that this result is consistent with existing theories of unemployment hysteresis that focus on depreciation of human capital and search activity during unemployment spells.

Inflation,Unemployment and Hysteresis: An alternative view

This paper integrates ideas concerning the influence of the interest rate on the rate of profits with an analysis of inflation and its relation with unemployment. Inflation is regarded, as in Kaleckian contributions, as resulting from inconsistent claims on income, but the approach taken leads to different conclusions concerning the effects of inflation (or deflation) on income distribution, and the circumstances giving rise to acceleration of inflation. The approach followed in the paper also provides explanations of phenomena that have appeared 'puzzling', particularly the association of different unemployment rates with stable inflation, and the persistence of high rates of unemployment.     

A new approach to testing unemployment hysteresis

This paper proposes a novel approach to testing unemployment hysteresis. It examined the existence of hysteresis in the unemployment rates of four Nordic countries, namely Denmark, Finland, Norway and Sweden, for the period of 2000–2014. The study applied four alternative methods to analyse the data. The best estimation procedure was chosen in a simple and consistent way. As the findings indicated, the ADF test and FADF test failed to reject the null hypothesis of unemployment hysteresis in all four countries. The ADF–SB test produced mixed results: it rejected the null hypothesis of hysteresis for Denmark and Norway, but failed to reject the null hypothesis for Finland and Sweden. The FADF–SB test yielded more consistent findings: it rejected the null hypothesis for all four countries. Furthermore, findings from the F-tests clearly indicated that the FADF–SB test was the best method among the four proposed alternatives. Despite some discrepancies the findings of this study suggest that unemployment in the four Nordic countries had a mean reversion tendency.     

Unemployment hysteresis - macro evidence from 16 OECD countries

This paper investigates empirically the presence ofunemployment hysteresis in 16 OECD countries, applying aggregate quarterly unemployment rates covering the past 25 years. Alternative test procedures are discussed and employed, posing both stationarity and hysteresis as null hypotheses. The results suggest that hysteresis effects are highly significant in Australia and Canada, and to a lesser extent also significant in most European countries and in Japan. Only in the USA, the presence of unemployment hysteresis is strongly and consistently rejected.Without attributing to them opinions or errors in the paper, I wish to thank Steinar Strøm, Ragnar Nymoen, Arvid Raknerud, Anders Rygh Swensen, Jeremy Smith and two referees for helpful comments.
